Zzz...
I am overtired today. I stayed up too late last night, helping some online friends progress through an online game. The process takes a couple hours commitment, and leaving in the middle is awkward and frustrating for everyone, so if the exercise takes longer than expected, it can make for a late bedtime.
When I’m overtired, I’ve found there’s no point in doing any significant writing. The time spent is not merely less valuable then an equal time spent on a better day, it actually has negative value: I end up amending existing text so badly that I have to spend even more time the following day fixing up the mistakes created in the process. Better to leave existing text alone. Better to spend my work hours reading for useful quotes, or simply doing housework. Or write for the exercise itself, as I am now, developing good habits.
The final product is hardly worth the effort, though. Perhaps you noticed.
